Thebore of the tubular portion 21 is extended through the bottom section 15to form a discharge passage 23 for the contents of the container 10. Theouter or upper end of the cylindrical portion 21 is provided with anannular inturned lip 24 to constrict the outer or upper end of thepassage 23. An intermediate portion of the discharge passage 23 isprovided with a valve seat integralwith the cylindrical portion 21. InFigures 1, 2 and 3, they valve seat is formed by a wall 25 extendingtransversely of the discharge passage and having an axial opening 26therethrough.

The mounting member is permanently secured in the container neck byengaging the bottom section 15 in the constricted throat portion 12 withthe bulbous section 17 abutting said throat portion. Then a downwardpressure is applied simultaneously to the upper end of the spoutshoulder section wall 18 and to the upper end of the bottom section 15,which is the bottom wall of the well 22, whereby the bulbous section 17is flexed around the constricted throat portion 12 of the containerneck. The well 22 will permit the exing of the bulbous section 17 aroundthe constricted throat portion 12. Due to the inherent characteristic ofthe material of the mounting member, such as polyethylene, to assume itsoriginal condition, the bulbous section 17 will tightly engage aroundthe constricted throat portion 12 and wedge the mounting member in thecontainer neck to form a -liquid-tight and tamper-proof seal. Thedownward pressure applied tothe bottom section 15 and to the top section18 will also cornpress the shoulder section 18, 19 into the shoulderportion 13, 14 to form a second liquid-tight seal between the containerneck and the mounting member. Flexing of the cylindrical portion 21 in alateral direction will not loosen the mounting member in the containerneck, but will have a tendency to place a tension on the lower part ofthe bulbous section 17 against the lower part of the constricted throatportion 12. Downward pressure on the cylindrical portion 21 will notloosen the mounting member in the container neck, but will have atendency to tighten the engagement between the walls 13 and 19 and urgethe bulbous section 17 against the constricted throat portion 12. Anupward pull on the cylindrical portion 21 will not remove the mountingmember from the container neck as said pull liexes the bottom-section 15outwardly against the tapering base portion 11 of the container neck.The top section wall 18 is of greater length than the neck wall 14 andduring the compression of the top section 18, 19 into the shoulderportion 13. 14, the upper part of the top section wall 18 will expandlaterally over the top edge of the shoulder portion wall 14 whereby itis not possible to insert an instrument between the top section wall 18and the shoulder portion wall 14 to pry the mounting member loose fromthe container neck. Due to the resiliency of the mounting member, thedownward pressure applied thereto in securing the mounting member in thecontainer neck will not collapse the container top wall.

It is to be understood thatthe mounting member is adapted to be securedin or attached to other types of containers than that disclosed in thedrawing.

The other member of the embodiment of the invention, as shown in Figures1 to 5, inclusive, is a valve-spout member of resilient material, suchas polyethylene, and comprising a tubular portion 27 having aliquid-tight sliding tit with the constricted end 24 of the dischargepassage 23 and an enlarged portion 28 at the inner end of the tubularportion 27 and having a straight side wall sliding in the dischargepassage 23 above the valve seat 25, 26. The tubular portion 27 isprovided with an axial bore 29 extended partially into the enlargedportion 28, as shown in Figures l, 2 and 3, and communicating with aport 30 extending laterally through the lower section of theienlargedportion 28 on one side of .the longitudinal axis of the valve-spoutmember, wherebyv the bore 29 communi- .cares with the discharge passage23. The communication of the bore 29 with the lower portion of thedischarge l 28 is adjacent to or abuts the inturned lip 24, the pin 31is fully disengaged from the opening 26, as shown in Figure 1, and whenthe lower end or the bottom of the enlarged portion is adjacent to ora'buts the wall 25, the pin 31 is fully engaged in the opening 26 withthe conical end 32 extending below the wall 25, as shown in Figure 2.The port 30 extends radially of the pin 31, as shown in Figure 4.

To discharge the contents of the container, the valvespout member ispulled upwardly to disengage the pin 31 i from the opening 26 and thecontainer 10 is inverted to cause the flow of the contents from thecontainer into the lower portion of the discharge passage 23 and throughthe opening 26 into the upper portion of the discharge passage 23 andthence to the bore 29 through the port 30.

The rate of tiow of the contents of the container through vthe bore 29can be controlled by the extent the valve-spout member is pulledupwardly in the mounting member, as shown in Figure 3, wherein theconical end 32 is partially positioned in the opening 26.

To discontinue the discharge of the contents from the container, thevalve-spout member is pushed into the mounting member to fully engagethe pin 31 in the opening 26, as shown in Figure 2.

To facilitate the breaking of the liquid-tight engagement between thepin 31 and the opening 26 when it is desired to discharge the contentsfrom the container, the section of the tubular portion 27 extendingabove the mounting member cylindrical portion 21 is provided withlongitudinal knurls or tintes 33 so that the valve-spout member can besimultaneously rotated and pulled in an upward direction.

Figures 6 to 9, inclusive, show modified forms of the valve seat in themounting member and the enlarged portion of the valve-spout member. Themodified form of valve seat comprises a wall 34 integral with thecylindrical portion 21 and extending transversely of the dischargepassage 23. Said wall 34 is arranged with openings 35 in diametricallyopposite portions of the wall 34 and a pin Aor projection 36 integralwith said wall and extending upwardly therefrom. The modified form ofenlarged portion of the valve-spout member comprises a spherical portion37 at the lower end of the tubular portion 27 of a diameter to form aliquid-tight sliding fit with the inner wall of the cylindrical portion21 above the valve seat wall 34. The spherical portion 37 is providedwith an axial opening 38 corresponding to the size and shape of thevalve seat pin 36 to form a liquid-tight sliding tit with said pin whenthe valve-spout member is moved into the mounting member. The opening 38is in axial alignment with the bore 29 of the tubular portion 27 and theupper end of the opening 38 communicates with the lower end of the bore29. The diameters of the valve seat pin 36 and the opening 38 aregreater than the diameter of the bore 29. tion 27 in the modified formof the enlarged portion 37 shown in Figures 6, 7 and 9 is smaller thanthe diameter of the bore 29 of the tubular member 27 shown in Figures l,2 and 3. The advantage of the modified forms shown in Figures 6 to 9,inclusive, is that the valve-spout mem- 'ber can be accidentally tiltedor tipped in the mounting member without breaking the liquid-tight sealbetween the spherical portion 37 and the inner wall of the cylindricalportion 21.

The operation ofthe modified forms shown in Figures 6 to 9, inclusive,is the same as the structure shown in Figures 1 to 5, inclusive, wherebyin the lowermost posi- The diameter of the bore 29 of the tubular por-'tion of the valve-spout member in the mounting member, the opening 3Sengages the pin 36 and closes the communication between the dischargepassage 23 and the bore 29, and the container is sealed. In theuppermost position of the valve-spout member in the mounting member, thecommunication between the discharge passage 23 and the bore 29 is openand the contents of the container is discharged upon tilting orinverting the container.

Due to the resiliency of the material of the mounting member and of thevalve-spout member, the valve-spout member is readily assembled in themounting member by forcing the enlarged portion 28 or 37 past theinturned lips 24.
